AUBURN, NEW YORK, A CORPORATION OF NEN YORK SHOE FORM Application filed April 25,

This invention relates to improvement in show forms more particularly those which comprise a hollow toe member of resilient material such as celluloid and a cross bar suitably attached to the walls of the toe member so that by the movement of the cross bar the width of the toe member may be increased or decreased.

This invention is shown and described as applied to a toe member having ball flanges, one end of the cross bar being pivotally mounted on one of the flanges and the other flange being provided with guiding means which coact with the cross bar so that the pivotal movement of the cross bar causes an increase or decrease in the width of the toe member. In adjusting the toe member to the proper width it is desirable that the pivotal movement of the cross bar be a slow or gradual one so that it can be quickly checked when the desired width is attained.

One object of this invention is to provide frictional acting means which will continuously resist this pivotal movement ofthe cross bar and more particularly to provide frictional means of the same material as that of which the toe member is made. Another object of this invention resides in the provision of an element preferably, though not necessarily in the form of a disc, movable by the cross bar over the flange of the toe memher and in contact therewith and which may be of the same material as that of which the toe member is made. A further-object of the invention is to provide a friction element which, when the cross bar has been swung to that position which gives the toe member the proper width, may be rigidly secured to the flange thus preventing any movement of the cross bar out of the desired position.

Other objects of the invention will appearfrom a consideration of the following specification taken in connection with the draw ings which form a part thereof andin which.

Figs. 1 and 2 are bottom plan views of shoe forms embodying this invention and differing from each other in the means of associating the cross bar with one of the flanges of the toe member;

Fig. 6 is a sectional view along the line 66 of Fig. 5; and

Fig. 7 is another sectional view along the line 77 of Fig. 5.

The toe member of the shoe form illustrated in Figs. 1 to 4 inclusive is designatedby the numeral 10 and includes opposite side walls 11, 12 which terminate in ball flanges 13 and 14 respectively. The walls 11 and 12 of the toe member are joined by a cross bar 15. pivotally connected at one end to the flange 13- by a rivet 16 or other suitable means. In the flange 14 is formed an arcuate slot 17 which receives a button 18- or other form of movable member attached to the other end of the cross. bar 15. Mounted upon the button 18-between the end of the cross bar 15 and the flange 14 is. placed a disc 20 preferably of the same resilient material as that of which the toe member is formed. The disc 20 is in frictional contact with the upper surface of the flange 14 so that the frictional engagement resists the pivotal movement of the cross bar 15.

When the cross bar 15 has been. moved into that position at which the toe member 10 is of the proper width it may be fixed in that posi tion by attaching the disc 20 to the surface of the flange 14. If the disc 20 be, as is particue larl-y desirable, of the same material as the toe member, preferably celluloid, this secure ment of the disc to the flange may be done by inserting acetone between the surfaces. Fig 4 illustrates somewhat exaggeratedly a layer 21 of adhesive between the disc 20 and the flange 14. It will be understood, however, that the adhesive here indicated is very much enlarged in order to bring out this feature and that, as a matter of fact the two surfaces would be integrally joined if acetone be supplied to the surfaces in contact.

The embodiment shown in Figs. 5, 6 and 7 differs from that previously described merely in the manner of resisting the pivotal movement of the cross bar. The same reference characters therefor will be used to designate the parts in common and no particular description of such parts or of their coaction is believed to be necessary. In place, however, of the disc 20 shown in the first embodiment there is provided an elongated boss 30 which is struck up from the surface of the flange 14 as is most clearly shown in Figs. (3 and 7 The crown of the boss 20 bears against the cross bar 15 and thus ofi'ers resistance to the free pivotal movement of the cross bar. The boss 30 is preferably arcuate and can be struck up at the same time that the slot 17 is formed in the flange 14.

In both of the embodiments described it will be noted that the free pivotal movement of the cross bar 15 is resisted by frictionally acting means preferably of the same material as the toe member. The first embodiment, however, discloses in addition to this feature that of permanently securing, the cross bar at any desired stage of its pivotal movement. A shoe form of the type shown in Figs. 1 to 4; inclusive may be made up in quantities and supplied to manufacturers and other users. These shoe forms are then set to the widths of the shoes with which they are to be used and when the proper width has been attained the cross bar is held against pivoting from that position by the application of a suitable adhesive between the upper surface of the flange 14 and the disc 20. As pointed out above the toe members are usually made of such resilient material as celluloid and when so made the application of acetone will cause a fusion of the celluloid of the disc with the celluloid of the flange. If the disc 20 be made of material other than celluloid, it will, however, be rigidly secured to the flange hy the use of the proper adhesive. The use of adhesive to secure these parts in position is only one way of so doing and instead thereof the disc 20 may be attached to the flange by rivetsv or other forms of fastening means which are well known to those skilled in the art and which therefore are not illustrated.

The showing and description in this appli cation of two embodiments: only of this invention obviously does not limit me thereto since other embodiments of this invention can be made without departing from the spirit and scope of the invention as set forth in the following claims.
